I'd advise developing a secondary route after you get that BS in Biology. There is absolutely no job market for bachelors degrees in biology. I only know this because my girl finished with a BS bio major and chem minor. There are no jobs for her and all her friends who graduated with the same degree.

She just took the GRE (graduate school entrance exam) and starting to apply at masters programs for nuclear medicine, bio/chem research, and radiology. Most of her friends with Bio degrees that can't get into graduate programs (due to grades or GRE scores) are stuck working retail at malls or doing secretary work.

You have to make time for the gym, i even was able to. It took me damn 7 years to graduate college with an associates in Forensics and a Ba in criminal justice with a gpa of 3.5. At the time i was running a part time business, working a job from 7am-4 pm and home depot from 6-11 pm. Different days had school etc, but i was still able to get there, that included driving 300 miles per day as well, sometimes 200 if i got lucky. I was tired all the time, did suck alot i cant imagine doing it again. Great job man, wish i had the money to further my education.
